From your result, it looks like A6-5400K supports BR 3D (both MVC decode and Frame packing output). I will try to obtain A6-5400K and report back.

Done. A6-5400K supports BR 3D (both MVC hardware decode and frame packing output) just fine. Here is a CPU usage graph at playing back Cloudy ... with PowerDVD 12 (the black window is PowerDVD; note that Trinity supports Frame packing in windowed mode, unlike Llano).

The motherboard is the MSI FM2-A75IA-E53. The power supply is the Realan 12V180W DC powerboard with a 12V150W AC adapter. I have it running in the Realan E-i7 case with the stock AMD cooler and one Gelid 80mm fan. Other components are 8GB DDR3-1866 running at 1866 (Profile 1), 128GB SSD and a Toshiba slot-load blu-ray.
I honestly can't get over seeing my Kill-a-Watt dip below 20W and Speedfan reporting 35C in that little case with stock cooling!
FM2 mini-ITX: feast or famine.

That powerbrick is probably helping you get the 20W, they seam to be about a 5-15W improvement over your standard setup.

renethx, nice work. Thanks for the definitive answer.

Do you trust that 35 C or do you need to add a 10 to 20 C offset like I did? I get 35 C after adding a 20 C offset in my Silverstone GD05B micro-ATX case.

I think I do -- at least the case was cool to the touch and the fan was running low and quiet. That's the real measurement for me -- how the case feels and how the fan sounds.

Thanks, did you test 2d-3d conversion?

What madVR settings are Trinity owners using? I'm killing some time tweaking my A8K. Currently running software decoding, Chroma Softcubic 100 with AR, Upscaling Lanc 4 with AR, Downscaling Catmull-rom w/ AR.
No dropped frames with BR content.

Cpu utilization floats around 29% in software (~50 on 2 cores, ~10 on a third, zero on the 4th). DXVA native decoding works in LAV, but I figured it would be better to offload to CPU to allow more freedom to play with MadVR scalers. I'm assuming that Trinity lacks the grunt for Jinc.

Since this chip is unlocked, I could overclock the GPU, but from the gaming benchmarks I've seen, it's probably ram bottlenecked anyway (I'm running 1866). The A10's 50% extra cores didn't seem to scale up much from the A8.
edit: at least for my mobo, overclocking the gpu to 800MHz (default a10 clock) works, but seems to disable CnQ for the GPU, i.e. it stays at 800 even when the GPU is idle.

Thoughts/ideas/snide comments/flames?

Decoding is done by UVD, while madVR algorithms are done by stream processors. They are independent. I recommend DXVA (native).

Jinc3+AR image scaling for SD/720 films is no problem even with A6-5400K. Jinc3+AR image scaling for SD/720 60fps contents will require HD 7770. Jinc3+AR chroma + image scaling for SD/720 60fps contents will require HD 7870.

CPU usage at 2D-3D conversion of a 2D 1080p24 film @3.6GHz:

Thanks. I'll test further. CtrlJ reports major frame drops playing Jinc3/AR 720p recorded TV (I assume 60fps) but I couldn't appreciate them. That matches your findings that it needs HD7770.

edit:
Testing with DXVA2 native, Chroma Lanc4/AR, Up Jinc3/AR, Down CM/AR. Seems stable with BR and DVD content.

Good info. I bought an A10 for another new htpc based on the info here...may have gone with the A6 had I seen this earlier, but oh well. These AMD's are so inexpensive anyways.

Are you going with stock cooler? I decided to buy a Big Shuriken 2 fearing that the stock was insufficient for the A10-5700. It seems like that might have been a bit overkill, although I like that it only needs to spin at about 500-600 RPM. I think the stock might be sufficient, although it could be loud.
